Beginning May 1, 1996, if an employer in one country sends the same employee to work
            in the other country on more than one occasion, the detached worker rule will apply
            to that employee for the second and any subsequent assignment only if:
         
         
            - 
               
                  • 
                     that assignment is expected to end within 5 years of the beginning date of the original
                        assignment, or
                      
 
 
- 
               
                  • 
                     at least 1 year has elapsed since the ending date of the most recent assignment. 
 
 
The same conditions apply to self-employed persons who transfer their business activity
            from one country to the other more than once. The detached worker rule will apply
            to the second and any subsequent periods of self-employment in the other country only
            if that period of self-employment is expected to end within 5 years of the beginning
            date of the first period, or if at least 1 year has elapsed since the end of the most
            recent period.
         
         Prior to May 1, 1996, the agreement did not include a specific rule applicable to
            successive assignments or periods of self-employment in the other country.
